Guidance on selection of job category

I am having nearly 6 years of IT experience and have also done distance MBA in Marketing. I have close to 2 years experience in Oracle Apps and then entirely into Oracle PL/SQL and slightly into SAP BO. I want to make my career in SAP line and later into Pre-sales. Kindly guide me shall I take some course in SAP BO and then try for job change

Your are having nearly 4+ years experience in to Oracle PL/SQL , why cant you continue your journey with the same, as salaries and future is also can be expected from that.You didn't mentioned how much experience you had into SAP BO.One of my friend is working on SAP BO he use to say calls are more for candidates having 3.5+ years experience on SAP BO.
